C/2017 S3 DEEP IMAGE LRGB Taken by Michael Jaeger on July 16, 2018 @ Weißenkirchen Austria

UT 23.50
L-9x150 UV/IR
5x180 blue
3x180 green
12/4 Asi 1600 2x2
The second outburst brightened the comet by 2m5 within three days. On the morning of July 17, he was already 8m0. A deep image showed a nearly 10 arc minute coma and a faint ion tail of more than half degree. After the first outburst, the comet was weak from 6 to 14 July.
Everything is possible now.
